The stanley blowers will push a lot of air until you try and hook it up to a carbon filter. There is no point in growing a pound of weed if the smell is going to be an issue. You will either be busted or robbed before you get to even smoke a bowl.
And no one has mentioned this guy is growing outside in a shed. That shed is just baking in the heat. You need to insulate that shit out of the shed so the outside temps don't affect the inside temps. Whether your shed is metal, plastic, wood, or whatever, the sun is just beating down on it all day. Your growing inside a giant oven.
Get your grow inside your house and you will save yourself a head ache. With out A/C you are not going to get your temps below ambient temps outside. So if in the summer its 100 degrees outside, no matter what you do, you will have at least 100degree temps inside. The more cfm you run the closer to ambient temps you can get, but when ambient temps are already above that which is acceptable, you are in a losing battle.
You either have to get an A/C unit out there, which will require you to run it on a differnt circuit than your other equipment. Or you can move your grow inside and use your central A/C to control temps. And there's always option number 3, just get the plants out of your shed and grow them with sun light.
